Question

What will be the pH of a solution made by dissolving a base in water?

(a) pH > 7
(b) pH = 7
(c) pH < 7
(d) any of the above

Answer 1

The pH of a solution resulting from dissolving a base in water will be greater than 7, indicating an alkaline or basic solution.

Step-by-step explanation:

The pH of a solution made by dissolving a base in water will be pH > 7. This is because the pH scale measures the concentration of hydrogen ions in a solution, and bases have a lower concentration of hydrogen ions compared to acids. As a result, a basic solution will have a pH value that is greater than 7, indicating it is alkaline or basic. For instance, household ammonia with a pH of 11.0 is considered basic. In contrast, substances with a pH of less than 7 are acidic, such as vinegar or lemon juice, and a pH of exactly 7 denotes a neutral solution, like pure water.
